Dr. Mason worked for a number of years (2002-2010) in the Caribbean in Trinidad and Tobago, Guyana, Grenada and several other Caribbean nations where he provided surgical services for the underserved while developing programs to improve medical services in these island locations. While working in Trinidad and Tobago, he was frustrated by the substandard conditions he found in this emerging nation, and he formed a company, Global Medical Centers of Excellence whose focus is to develop Medical Cities in a number of Caribbean nations as well as in Africa that will feature a Medical Center of Excellence (a 120 bed multispecialty hospital), a Nursing School and a Biomedical Research facility to improve the quality of medical care in these emerging nations. On returning to the United States in 2012, he began practicing surgery in Arkansas where he found conditions in the Delta similar in many respects to conditions he had experienced in some of the developing Caribbean nations with a medically underserved population. Responding to this great gap in US medical care, he formed a company focused on implementing strategies to deliver healthcare more effectively and efficiently to the Arkansas population and throughout the US. In July, he joined the staff of Mainline Health Systems, attracted by Mainline’s mission that aligned completely with objectives he was striving to achieve through his domestic health care company: to deliver the highest quality of personalized medical care to the Delta population that would set a new standard for health care delivery throughout Arkansas, and indeed the United States. Since joining the Mainline staff, he has been impressed with the zeal and dedication of his colleagues who, inspired from the highest levels of Mainline’s leadership, daily live their mission to serve the people of the Delta, delivering healing services exemplified by the Christian virtues of humility, respect and love.
